Application flled May 26, 1916. Serial No. 99,994.

To all whom t may concern Be it known that T. BYigziis WV. Kaum., 4a citizen of the United States. residing in Roanoke county, State of Virginia.` have invented certain new and useful Improvements in (lar-' llrucks. of which the following is a specification. l p

The present invention pertains toycar trucks and particularly to those having six wheels with three axles and the customary oil boxes on each end of an axle.

Among the obje :ts ot' the saine are to provide side ineinbei and bolster members of iniliroved cmistruction. `improved means in connection with the truck side nien'ibers for sui'ipoi'ting the truck brakes and for providing a cable guard. also to provide improveinents'in truck side ljiearings and center bearings v Other specific objects will appear as the present embodiment described.

The invention consists in the novel construction and arrangement ot' cai' and truck parts as will be set forth.

In the accompanying drawings. Figure 1 a plan view of a truck embodying t'catures of in v invention and Fig. L) a. side ele vational view ot.' the same.

Figs. llland 11 are transverse vertical sections through the side ti-allies. the saine being taken on the lilies F F and (ir G respectively oi Fig.

.lle't'erring to these drawings which show a preferred en'ibodiineut' oi in v invention. it willbi` een that the truck embraces a plurality ot wheels l mounted upon axles Q which are suppliediviltli the customary oil boxes 3. lilxtcniling along each side of the truck are side frames 4 and 5. the frames 4 resting at their ends on the oil boxes of another end axle and overlapping the frames -i at their other ends and resting` thereon.` The frames 4 and are articulated with re-vV spect to each othe' and with respect to` a horizontal plane. the transverse connecting pinsI tying the frames together and forln ingr the hinge point. The frame or uframes which are termed the rigid iramesa are made bifurcated at their inner ends forv a" portion of their depth but not for their full` depth there being a transverse wall of metalli 7 connecting and tying together tlieiside walls and 9 at or near the bottom` of tlief same. '.lhese side wallsaie spacedV apart and accommodate therebetween theover- "reaching end ot' the frame 5. there being some clearance provided between the walls` T and thc adjacent side otthe' frame 5 as to allow the said articulation. The top member 10 ol. the frame ft is made of chan'- nel shape in cross section with a substantially horizontal web 11 and vertical de-` pending HangesI 12. The web 1l and transverse member T may be said` to merge to-` gether. the side walls S and 9` constituting upward extensions from the normally depending flanges 12. These flange extensions thus foi-in a wavt'or the movable accommo-` dation therebetween of the over-reaching end of the Vframe The bearing of the frame upon" the frame Jr is made arcuate at 13. the center of the. pin being the center of thel arc.y 1n order to i'orm this arcuate pocket the web 1l" ot' the iranic -l is divertedt'rom its norninl path or convoluted. and the. flanges `1" are at the saine time extended upward to foring` side walls 1l for this pocket. the saine being pierced transverselv of the frame to accommodate the pin Outstanding Hanges 15.

are provided on the outer faces of these side" walls to stiti'en the saine. similar outstanding flanges 1() being also provided along the walls 8 and 9. A bracket or brace 17 is pro! vided between the channel fianges under the pocket at 13; l

' upper edges ot' the tlange extensions orside i .Iliere `is some lateral clearance provided between the walls vS and 9 `and the framei'i,y

and :in order to.1iinit-,tl`ie movementbetween the outer end of the frame drops below the "rail the clearance between the wall 7 and the 'under side of the frame 5 may not suflice for the necessary articulation. The pierced hole 19 in the end of that frame for the pm 6 ing upon the other at the center of its length I' springs 33 in .the side frame window vrinner end ofthe frame 5 `by an additional/tie member 26. The botmiddle truck wheels.

is .elongated in a suitable direction so that if the frames contact there will be no binding but the inner end of the frame 5 may move along the slotted hol'el19 and relieve any such blndmg.

yThe side frames are made with the customary bolsterwindow openings 20 with top compression 'members 21 and bottom tension members 22, these latter forming frspring seats.

At the sides of the bolster openings are the vertical struts 23, and extending from over and under the bolster openings and converging at their ends are the top and bottom arch members 24 and 25, the same being tied together at their ends.

The arch members 24'1 Vand 25a for the are tied together tom member25a is bent out` of a normal path ait 27 and the diagonal tie 26 extends from this bend to the rigid unction of the member 21, the member 24a and thel adjacent member 23. Thus the inner end of the frame 5is provided 'with a plurality of triangularly shaped openings, the one being defined by the bottom arch member' 25, the

adjacentstrut 23 and the tie member 26,-

the other by the bottom arch member 25a, the top member 24 yand thev tie member 26.

The bolster'construction consists of a pair of transverse members 27 and 2S which pass through the side frame window openings and are disposed along either side of the These support a longitudinal bolster member lor center bolster 29, the-center bolster being cast integral with'one cross bolster at 30 and rest'- at 31 in a suitable window opening 32.

The cross holsters are of I shapein cross section, the Webs being vertical and there being normally horizontal `top and bottom flanges. These cross holsters rest on the openings, the bottom flange of a bolster forming its spring seat or bearing. This spring seat is horizontal within the limits'of the side frames and the bottom flange then drops -downwardly toward the center of the truck.

The top flange extends from its outer end on an upwardly inclined plane toward the center ofthe truck until inside of the side frame lines when it also drops downwardly so that at the center the entire cross bolster is depressed to accommodate the draft sills 34` of the c ar body which areusually secured 'under the car floor.

I am thus enabled to provide a cross bolster of great strength to withstand the heavy loads to which it is subjected. The cross bolster` is v'also of I section with continuous and uninterrupted flanges extending from end to end. The openingr 32 is located in the depressed portion of the cross bolster or where it has been formed' out of a normal line, the longitudinal bolster seat being somewhat below the spring seat at the ends and the top flange of the depressed portion being substantially on line with the bottom flange at the spring seats.

The opposing sides 35 and 36-of the side frame bolster openings are flattened to form bolster guides, the inner edges 37 of the same being also shaped to serve as bolster stops. To coact with these, the ends of the bolster are provided .with additional side walls 3S which extend vertically froln flange to flange and are formed to tie together the flanges and coperate with the faces 35 and 36, these walls terminating at their inner 'ends in angular portions which extend around and form coacting stops on the bolster for. thel stops 37. These walls are also extendedv below the spring seat face of the cross bolster so as to provide additional strength and wearing surface and hold the springs in alinement.'

The window opening 32 in the cross bolster 28 is cut into the web of the same preferably 'Without disturbing and weakening the flanges, and there is provided for a longitudinal bolster seat van additional horizontal flange 39 which is widened out at its center and disappears into the web of the I at each side of the opening 32. Vertical flange members 40 are placed along the edges of the yweb where it is cut away for this opening, the same extending `from the flange 39 upwardly and defining the opening. Stiff'ening brackets 41"extend from the flange down to the main bottom flange of the I.

The longitndinal bolsterl 29 consists of substantial]yparallel members 42 which extend longitudinally of the truck and between the draft sills of the car and the middl e` truck Wheels. These are bumped over the middle axle and are cast at one end at 30 into one piece with the cross bolster' 27 which supports these ends at spaced points along its length. The parallel members converge vat their other ends along angular lines 43 and are dropped down and curved inwardly under the draft sills and are joined together at lthe center line of the truck where the tapered end 44 of the longitudinal. bolster` passes within the window 'tudinal bolster member l2.

and narrower at the opposite side. The end 44 of the longitudinal bolster is also tapered in depth Within the limits of the opening 32,`the opening being tapered to accommodate the same. 'Thus the end -i-.l of the longitudinal bolster may be greatl \T strengthened as it leaves the crossbolster.

The cross bolsters QT and .28 are formed at their centraligiortions with the top flanges or faces thereof `on an inclined plane longitudinally of the carz that is,` with their inner edges higher than their outer edges.

This provides space for graduallv deepen# ing or tapering the draft sills of the car as indicated in Fig. and in the case of the cross'bolster 28 forms a convenient way of "tapering theol'iening 3x2-for the accommtr dation of the verticallyv tapering end of the li'n'igitudinal bolster.

The central'portion of the longitudinal bolster 29 is constructed` as follows: At 45, is a circular. flat bottom center' bearing plate .with a separate co-acting saddle plate 4G Yresting thereon. The bottom face of the' "plate 4G is made flat and circular so as to conform to and rotate on the surface of the plate 45. The upper surface 47 of the plate 4() is made coi'ivcx, and ii'rreality constitutes a portion of a cylinder, the axis ofthesame being transverse of the truck. The plate 4-8 secured to the car body made concave to accommodate the c vlilulrical form of the surface 4T thus the plate 48 may revolve partiall)v about -the surface 4T longitudinally of the car to allow jfor al'igularitv of the trucks and car body on vertical curves. the rotatable relationship of the. surfaces and 46 allowing for angular-ity duc `to horizontal curvature of the track. At the same time.l when they car body tilts sidewise or rocks on the side bea ri ngs it will always return to its normal position.

The center bearing plate is suitably supported on a pair of flai'iged beam n'iembers 4) which are disposed longitudinally of the car and span over the middle axle. These are in turn supported upon a pair of transversely disposed laugedbeam n'ieniliers '5.0

,which are disposed' along either side of the niiddle'axlc and all of which are made in Ithe one integral casting. In turmthese extend to and are supported b v the main longi- The beam members 49 and 50 are preferablyT `located so that their webs fall within the linesof the circle of the renter plate so that tliere are formed rhordal braces under each quarter ofthe same. This constructirm stiffens and siipi'iortsy the center plate against the severe `and "coi'icen'trated loads to which itis subjected, as for examllile, in rocking on theiside bearings. At the same time the metal forming the Hoor of the center plate serves also as the top flange material for these beam 1nenibers.'tlie floor of the' center plate and the top flange of these beam members being in the same plane. The beam members 49 and 50, and espe- 4ciallv the members 50 are, as has been stated`r sections with top and bottom ianges, and I have provided a.v peculiar and improved method of joining the ends ofthe members 50 to the flanged members 42. The lower flange 51 of a beam 50 is lower than the bottom flange of the member 42. It is carried out preferably under this flange and then turned up and joined to `the under face of the same at 52. The top flange 53 ofthe meml'ier 50 is carried directly outward and' joined to the web of the member 42 between the flanges thereof.'

The lower flanges of the beam men'ibcrs` 49 are higher than those of the beams .50,and

these flanges contimle outward and terminate in the webs of the men'ibers 50 being cast thereto in a single piece.

lVhile in the drawings certain portions of truck brakes are iflisclosed, the present application does not attempt to include all of' these brake features. portions of which will be made the subject of a future amiilmition for` Letters latent in thatV art. l 1

The special features of my truck, however. that relate to the l'iecessary adjunets of a truck inv order that itmay receive brakes are included herein and will now be set forth. In six-wheel trucks of this character it has heretofore been customary to support the brakes from brackets extending outward from the side frames.

ln my construction I 'provide the sidc frames with rpockets 54 and 55, these having their inner faces open and their outer faces substantially closed. These may be below the spring seats of the side frames. llxtending across the truckf|`om side frame to side frame are crossbars 56 and 57 which rarr \Y brake hanger brackets 5S and 59. ',lhese brackets being carried b v the crossbars have no material n'loven'lent `with respect to the frames. the pockets restraining the cross bars against'axial. movement as well as movement in an \y plane. 'lhe cross bars are simply inserted within these open side l'iockets and the frames drawn up` into place. Then the keepers (3() are, applied to the outer ends of the cross holsters the side frames-'cannot part and consequently the bars o and `57 cannot get out of place. At the same time the brake hangers have no rigid ci'nmeetion. as bv c: ting or riveting. with thesideframes so that brake forces will` be .transferred to the frames as direct vertical `loads with`out theusual side forces that acemminv" the 'vertical "loads" `"The `cross bai" 56 is' made "of cast loo with the bracket 58 integral. The central portion of this bar is provided with ways or guides G1 for the brake members G2. T e cross bar 57 is made of a commercial I bzim laid the fiat way, that is with the web Horizontal. The bracket 59 is riveted to the webof this I and has a portion (i3 extending outwardly and supplementing Athe' I to fill out the pocket This cross bar 57 carries at its central portion a cable guard 64 which is a shaped plate overlapping the depending flanges of the I. Such a guard is required -at` points where a cable is used to haul cars up an incline and the I beam cross tie thus transfers the forces ot' this uplifbof. the cable to the side frames. Tothe one edge of this I, near the center is ailixed a bracket 65 which serves as a brake lever fulcrum. This I beam c rossbar thus transfers the brake fillcrum forces to the side 'frames These cross bars extend across the truck beneath the brake beams and. beneath .the cross holsters, the brake hanger brackets extending upwardly as between the backs of adjacent beams GG and then extending outvwardly over the beams. From these points swinging hangers G7 extend downwardly to directly support the brakes. In trucks of this character it is necessary to supply side bearings such as G8 and these ray be carried on bars or beams 69 extending from cross bolster to cross bolster. These are located preferably just inside of the middle truck wheels. The bars G9 rest on the cross bolsters. preferably on the top flanges thereof in suitable ret ining pockets and these bearing points are so arranged that the parts are not rigidly secured together as by bolting or riveting but simply rest one upon the other to allow the necessary movement or liexibility to secure the vertical articulation between the two cross'bolsters with respect to a horizonal plane. l

In order that the stability of the bars 69 with respect to a vertical plane may be assured there are provided extensions such as 7() from one or more of the members at their supporting points and these are adapted to contact the other member and secure -thefarched bars (S9 against tilting trans-y mitting the necessary fiexibility of tlie bols ster construction, will be retained. in 'their vertical positions. I
